State the conditions of total internal reflection.

In total internal reflection_____

State the conditions for ideal solution.

What do you understand by total internal reflection?

When a light ray travels from one medium to another and gets refracted, velocity of light becomes double. For total internal reflection in this condition, the value of critical angle is

At what angle should a ray of light be incident on the face of a prism of refractive angle 60^(@) so that it just suffers total internal reflection at the other face? The refractive index of the material of the prism is 1.524 .

A ray of light travelling in a transparent medium falls on a surface separating the medium from air at an angle of incidence of 45^(@) . The ray undergoes total internal reflection. If mu is the refractive index of the medium with respect to air, select the possible values (s) of mu from the following

Why is total internal reflection called total?
